why do cd players "sometimes" not read a disc?

My Lexicon RT-20 is sometimes refusing to read a disc that has just been playing?

It cost $89 so no big deal but if a CD player drive dies, a different story. Back up your music!

I have been pleased with its sound; but I found it benefited "dramatically" with ac isolation and conditioning. I found conditioning and isolating the ac provided a quite remarkable transformation. It makes me very curious about what internal parts related to power supply should be upgraded, and how.
